Winter Roadway Service Tool

Winter can bring challenging road conditions, but we’re here to help keep you safe. Our roads have clear timelines for snow and ice removal. This page explains how long it takes to clear your street and what happens during severe weather events.


Road classification and level of service

In Ontario, roads and highways are grouped into different categories called classifications. These classifications are based on factors such as how busy the road is, its speed limit, and its size. Each class has specific snow and ice maintenance timelines to ensure safety and accessibility.

You can find your road class using the property look-up tool below. Then use this table to learn what you can expect for maintenance timelines.

Significant weather events

When a significant weather event is declared, it pauses the regular timelines for winter maintenance. After the event ends, the City resumes its usual timelines. 

Significant weather events affect road and sidewalk conditions. During these events, everyone needs to be extra careful when travelling, because it may take more time to return streets and sidewalks to normal.
